摘要
以引黄水库水为实验原水,通过颗粒计数和浊度的联用检测优化评估了高锰酸钾强化常规处理工艺中的各制水环节的处理效果。结果表明,絮凝出水>10μm颗粒数和过滤出水2~7μm颗粒数的可作为水厂运行管理的依据,滤后水的颗粒物数量变化比浊度更灵敏准确地反映滤池运行状况;在高锰酸钾强化预处理的最佳投加量为0.8 mg/L时,原常规工艺沉淀对颗粒总数的去除率提高20.55%,滤后颗粒总数减少56.40%,显著降低了'两虫'穿透滤池的风险。
The combined application of particle number and turbidity was used to optimize and evaluate treatment efficiency of potassium permanganate for enhancing conventional water treatment with Yellow River reservoir water as raw water. The results showed that > 10 μm of flocculation effluent particles and 2 ~ 7 μm of filtered water particles could be used as the basis of water plant management. Filtration conditions corresponded with the effluent particle number better than turbidity. When the dose of potassium permanganate was 0. 80 mg / L,the removal rate of total particle number was improved 20. 55% for precipitation,and the total particle number decreased 56. 40% for filtration,significantly decreasing the risk of giardia and cryptosporidium penetrating filter.
